The responder, answering machine or message machine, also known as answering machine (or TAM) in the UK and some Commonwealth countries, ansaphone or ansafone (of a trade name), or telephone answering machine (TAD), is used to answering phones and recording call messages.
Unlike voicemail, which can be a centralized or networked system that covers, and especially extends, similar functions, an answering machine is installed in the user's premises along with the user's fixed telephone. Unlike operator messaging, the caller does not talk to a human. As terrestrial lines become less important due to the shift to cell phone technology and the maturing of unified communications, the installed base of TADs is shrinking.
Most twentieth-century answering machines used magnetic recordings that Valdemar Poulsen invented in 1898. However, the creation of the first automatic automatic telephone answering device is in dispute. Clarence Hickman worked for Bell Laboratories since 1930, where he developed methods for magnetic recording and working on the recognition of speech patterns and electromechanical switching systems. In 1934, he developed a tape-based answering machine that the AT & T phone company, as the owner of Bell Labs, was kept secret for years for fear that an answering machine would result in fewer phone calls. Many claim that it was William Muller in 1935, but could have been created as early as 1931 by William Schergens whose device uses phonograph cylinders. Ludwig Blattner promoted an answering machine in 1929 based on his magnetic recording technology Blattnerphone. In 1935 the inventor Benjamin Thornton developed a machine to record voice messages of the caller. The device, reportedly, was also able to keep track of the time the recordings were made. Although many sources contend that he invented it in 1935, Thornton had actually filed a patent in 1930 (number 1831331) for this machine, which used a phonographic record as the recording medium.
A commercial answering machine, the Tel-Magnet, offered in the United States in 1949, reproduces outgoing messages and records incoming messages on a magnetic wire. It was priced at $ 200, but it was not a commercial success.
In 1949, the first commercially successful answering machine was the Electronic Secretary created by inventor Joseph Zimmerman and businessman George W. Danner, who founded Electronic Secretary Industries in Wisconsin. The Electronic Secretary used the state-of-the-art technology of a 45-rpm record player for announcements and a cable recorder for message capture and playback. Electronic Secretary Industries was purchased in 1957 by General Telephone and Electronics. Another commercially successful answerer was the Ansafone created by inventor Dr. Kazuo Hashimoto, who was employed by a company called Phonetel. This company began selling the first answering machines in the United States in 1960.
Answering machines became more widely used after the AT & T restructuring in 1984, when the machines became affordable and sales reached one million units per year in the United States. While early answering machines used magnetic tape technology, most modern computers use solid-state memory storage; some devices use a combination of both, with a solid-state circuit for the outgoing message and a cassette for incoming messages. James P Mitchell exhibited a working prototype of a digital outgoing message with an engraved inbound system at an Iowa State University VEISHEA engineering opened in April 1982. This system won a Golden Award from the Engineering Department. In 1983, Kazuo Hashimoto received a patent for a digital answering machine architecture with the US patent 4,616,110. The first digital answering machine brought to market was the AT & T 1337; an activity directed by Trey Weaver. Mr. Hashimoto sued AT & T, but quickly dropped the trial because AT & T's architecture was significantly different from its patent.
